lQNlFE-SHARPENER FOR DOUBLE-PlLE-=FABR!C LCOMS.

SPECIFICATION forming part of Letters Patent No. 399,293, dated March12, 1889.

Application filed July 27, 1887. Serial No. 245,404. (No model.)

To all 207mm it may concern.-

Be it known that I, ROBERT SLuoN, of \Vechawken, Il'udson county, NewJersey, have invented certain new and useful Improvements in Sharpenersfor Knives in Velvet and other Looms, of which the following is a full,clear, and exact description. 7

l l e retofore in velvet-looms, plush-looms, and the like, in which adouble fabric is woven to be sol'rarated by a pile-cutting knife, theknife for cutting the pile has been commonly passed over a yielding honeor shar 'rener. The continued passing of the knife over the sharpenerwould wear a groove in the latter, and also leave thereon a deposit ofsteel, &c., all of which. would interfere with the sharpening of theknife. i

The object of my invention is to overcome these objections and toprovide a movable sharpener, so that the knife will pass over adilferentpart of the sharpener after each cut in the fabric, and therebyca use an even wear on the sharpener.

The invention consists in the combination, with a movablehone-carri er,of mechanism for intermittingly moving it and changii'ig its position,so as from time to time to present a differentportion of its surface tocontact with the knife.

The invention also consists in special means for movi n the hone-earrier after each passage of the knife, and in details ofconstructioi'i and combination of parts, as will be more fullyhereinafter-set forth.

Reference is to be had to the aco unpanying drawings, forming part ofthis specification, in which one mode of carrying my invention intoeffect illustrated; but. other mechanism for moving the hone-carrier maybe used and will readily suggest itself to any skilled mechanic.

A in the drawings represents a portion of the frame of a loom of theclass on which velvet or the like is woven. l3 is a knife carried by aclamp, a, the end I) of which clamp is adapted to slide in a groove, (I,in the loomframe A. The clamp (1 is secured to a band or other carrier,6, which has reciprocating motion imparted to itby suitable means. Thisgives the knife l a lo-and-fro motion. D represents a piece of velvet,which in Fig. 1 is shown as being wound on two cloth-beams,f

1, after the pile has been cut by the knife ll. E represents part of thebatten of the loom. These parts are all of well-known construction andneed no further description.

l is a slide mounted in bearings in a frame, G, which is attached to theframe A of the loom. The frame G carries an upwardly-projecting lug, g,which is adapted to be secured to a projection, 71., on a cross-beam, a,of the frame A. (Best seen in Fig. l.) The lug g has a slot, throughwhich passes a bolt, 11, said bolt also passing through a hole or slotin the projection 71 to permita proper adjustment of the frame G. Theslide F carries an upright or projection, 7, to which is pivoted at lthe lever ll. On one end of theleverllis secured Near the opposite endof the lover or houecarrier II is attached a spring, in, the other endof which is attached to the slide if or to the frame.

In Figs. 1. and L of the drawings are shown two frames, G, each carryinga slide, F, lever II, and sharpener .l. In 1 these frames are shownarranged at an angle to each other. The sharpener I on one lever ll,Figs. 1. and 2, is shown on the under side of said lever, while on theother lever ll it is shown on the upper side. The spring on at the leftin Fig. 1, at the right in Fig. 2, and in Figs. 3 and :l: is shownattached to the lever ll. outside of the pivot 7 which tends to raisethe long arm of the lOYOl'lT, and thereby the sharpener I. The spring onin the foreground in Fig. l and at the left in Fig. 2 is shown connectedto the lever H between the sharpener I and its pivot P. This tends tolower the long arm of the lever H, and thereby the sharpener I. A stop,a, limits the movement of the lever II On its pivot. The sharpeners Imay also rest in part upon a bevel, 0, on the cross-bar t in the frameA, Figs. 1 and 2.

The slide F carries a downwardly-projecting pin, p, which bears againstthe face-0f a cam, J, rigidly secured on a shaft, q, journaled inbearings in the frame G. The shaft (1 also carries a worm-wheel, 7',which gears with a worm, s, that is journaled in the frame G. ()n oneend of the worm sis secured a ratchet-wheel, L. A lever, 25, is pivotedto the frame G near the ratchet-wheel L, and carries a pawl, n, which isadapted to engage said ratchet-wheel L. A spring, '11, secured to theframe G, acts upon the lower end of lever t; A spring-click, 'w, actsagainst the ratchetwheel L to prevent reverse motion thereof.

M is a bracket secured to the batten andadapted to actuate the lever 25.I have described these parts as applying to one instrument, although inFigs. 1 and 2 are shown two instruments. This description applies withequal force to both.

The operation is as follows: Suppose the knife B to be in the left-handpart of Fig. 2. The knife B now begins to move in the direction of thearrow f Fig.2. It first passes along the face of the sharpener I whichis on the under side of the one lever ll, and then over the face of thesharpener I which is on the top of the next lever H. As the knifecontinues to move, it cuts the velvet D in the ordinary manner. At thefirst throw of the batten to beat home the weft the bracket M strikesthe end of the lever t,whieh, through pawl 11, moves the ratchet-wheel La suitable distance. This movement imparts motion to the cam J, which inturn, pressing upon the pin 1), moves the slide F, and thereby thesharpener I, in the direction of the arrow N, Fig. 2, a slight distance.As the knife comes back to the first position described, it passes overthe sharpeners I I; but as said sharpeners have beenmoved a slightdistance, as stated, the knife B does not touch them at the same pointit did before. Each time the batten is moved to beat the weft thesharpeners are moved a short distance until the cam J has made, say, onerevolution, and

until the pin 1) comes opposite the narrow orreceding part 00 of saidcam J. At this moment a spring, N, secured at one end to the slide F,and at the other end to a proj ection, y, on the frame G or frame A,draws the said slide F backward or in the reverse direction to which ithad been moving, ready to start forward again by the motion of thebatten M, the lever I, and thereby the cam J, as before stated. Fromthis it will be seen that the knife passes over a different part of thesharpener at each passage. This prevents the formation of a groove inthe sharpener, as is the case with the stationary sharpeners.

By placing the sharpeners I I at an angle, and with one at the top andthe other on the under side of the levers II II, I am enabled to sharpenthe knife with a proper bevel. By using two sharpen ers in one loom bothsides of the knife will be sharpened at one passage of the knife. Byresting the sharpeners on the beam to the proper angle will be insured,and the sharpeners will always be in their correct positions. Thehone-carrier may be operated by other means than by the batten andlever, if desired.

Having now described my invention, what I claim is 1. The combination ofthe reciprocating cutter B with the sharpener I and means, substantiallyas herein described, for moving said sharpener by degrees into the pathof the knife, so that said knife will pass over a different part of thestone after each cut in the fabric, as set forth.

2. The stationary frame G, combined with the slide F, means forintermittently moving the same, the lever H, and with the sharpen er I,carried bysaid lever, substantially as described.

The slide F, carrying the lever H, combined with said lever and withmeans for intermittently moving the said slide, and with the sharpenerI; substantially as described.

4. The pivot-ed lever H and sharpener I, combined with means,substantially as described, for supporting said lever and for movingsaid lever intermittently, as set forth.

5. The slide F and a spring for moving the same, the frame G, lever H,the sharpener I, and pin 1'), in combination with the cam J, and withmeans, substantially as described, for moving said earn, as set forth.

6. The combination of the slide F, lever H, o

the sharpener 1, spring N, pin 1), cam J, worm s and worm-gear r,ratchet-wheel L, lever t, and pawl 11, for moving the same, the lever ibeing adapted to be actuated from the batten E, substantially asdescribed, and for the purposes set forth.

7. The combination of the batten having a lever-actuator, the slide F,and the movable hone-carrier H, carried by said slide, with thereciprocating knife B, and with a cam, worms 0" and s, ratehet-wheel L,pawl "a, and lever 25, intermediate between said batten and saidhone-carrier, for moving the same by the batten, as specified.

8. The combination, in a loom, of the reciprocating knife B with twomovable honecarriers, H H, and mechanism, substantially as described,for moving both hone-carriers from time to time, so that the knife willpass over a different part of the hone after each cut in the fabric,substantially as described.

9. The slide F and movable hone-carrier II, earried thereby combinedwith the knife the hone after each out in the fabric, and 1-3 and therest or support a for said honewith the batten for actuating the lever,as carrier, and with a cam connected with the specified.
